Was your certification course entirely on line or did it include real teaching practice with actual students, and feedback from teacher trainers on how you've done?

If your course didn't include the teaching practice, you will be at a disadvantage on the job market in all the areas you name. Most newbies on this job market have a CELTA or equivalent, including the supervised teaching practice, and reputable employers look for this.

Also, keep in mind that there are start-up costs here. Because there are lots of teachers around, reputable employers don't need to take chances on anyone sight-unseen, so the way to find work is to come over, pick a city, and hand out your CV in person. The big hiring season is NOW, with a smaller bump in January.

If you haven't got the funds to do this, wait and save up until you do. It's not safe to go abroad without a reasonable financial cushion anyway. You'll need enough for your flights, probably at least two months' housing costs, plus a bit to spare. Employers usually pay monthly, at the end of the month worked.

(You're not qualified for the ME anyway - they pay well and demand real quals for the money - related MA + experience, normally).
